SHOWER HEAD.

i Application filed-October 24,` 1923. Serial No. 670,424.

To @ZZ whom t may concern:

Be it known that I, HENRY W.V A. LEH- Nnn'r, a citizen of the United States, residing at 657 East 24th Street, borough of Brooklyn, in the county of Kingsland State of New York, have invented certain new and useful Improvements in Shower Heads, of which the following is a specification. l Y

This invention relates. to the construction of Vshower headsI used to spray the water in shower baths.

The main obj ect of the invention is to provide a more sanitary and durable shower head than those heretofore used. Tothis end the shower head itself is made entirely of porcelain or the like, and is all in one piece.

By my construction I am enabled to provide a more satisfactory union between the porcelain shower head and the metal conduit to which it is connected. Furthermore I provide for the venting. of the head without marring the appearance of the head or destroying its symmetry, the vent opening being substantially invisible from the outside of the article.

Other objects and aims of the invention, more or less broad than those stated above, together with the advantages inherent, will be in part obvious and in part specifically referred to in the course of the following description of the elements, combinations, arrangements of parts, and applications of principles constituting the invention; and the scope of protection contemplated will appear from the claims.

In the accompanying drawings, which are to be taken as part of this specification, and in which I have shown merely a preferred form of embodiment of the invention,-

Figure 1 is a vertical transverse section through a shower head, and the water connection therefor, in accordance with this invention; and

Figure 2 is a transverse cross section taken on the line 2-2 of Figure 1 and looking vertically upward.

Referring to the numerals on the drawings, the body portion of the shower head is indicated at 4, and is preferably funnelshaped and formed of porcelain or similar material. p shaped body is closed by 'an' integral plate 5 in which there is a plurality of perferations 6 disposed in any,7 desired arrangement -feu" the outlet of the water. The small end of The large end of the funnel-v the funnel-shaped body 4 is providedY with an integral inwardly projecting annular flange 7 ,which passes freely a 'pipe connec* tion 8 having external ythreads 9; and the flange is provided with diametricallyl opposite openings or slots 10, through which may pass to the under side of the flange 7, ycorresponding lugs 11 extending in opposite directions at the end of the pipe connection 8.

It will be understood that after the lugs-11 have been entered through the openings 10 the pipe connection is given a partial rotation so that the lugs take the position of Figure 2. The upper or outer face of the flange 7 is depressed to provide a seat for an annular packing 12, this gasket in use being compressed by means of a nut 14 threaded on the pipe connection 8, so that a water-tight union is provided between the conduit 8 and the earthenware head 4. The flange 7 is perforated adjacent one of the side walls of the head, as indicated at 15, this opening 15 constituting a vent for the admission of airv to the head after water is turned off, so that the water may quickly drain from the head. The nut 14 has a flange part 16 which overlies the small end of the head and this flange part 16 is annularly grooved on its under face, as indicated at 17 ,.the said groove 17 registering with the vent opening 15. Preferably the gasket 12 is of sufficient thickness so that there will never be any likelihood that the nut 14 will be turned down so closely as to close off' the vent. It will be apparent that the vent opening is substantially concealed; also that if there should be any discharge of waterthrough the vent opening it will flow downwardly over the outer surface of the head, and not laterally. The provision of the depressed seat for the gasket I consider to be of importance, because the shoulder 18 of this seat limits the lateral expansion of the gasket under compression and insures a tight joint of the gasket with. the outer surface of the pipe 8.

Inasmuch as many changes could be made in the above construction, and many apparently widely different vembodiments of my invention could be made without departing from the scope thereof, it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.

Itis also to be understood that the lana guage used in the following claims is in tended to cover all the generic and speuiiie features of the invention herein described and all statements of the scope of the invention which, as a matter of language, 'might he said to fall therebetween.

I claim:

l. A shower head yincludingia Vperforated* outlet plate and an inwardly flanged top, the flanged top part being provided with a. depressed gasket seat and with a vent opening, the gasket accommodated in the seat, an externally threaded pipe connection extending through vthe gasket and through the iiangedpart of the top and engageahle under the lianged top, and av nut threaded on the pipe connection for compressing the gasket, said nut including a flanged part which extends over the flanged top portion and the vent opening therein.

2. The device setforth `in claim l in which the vflanged part or' the nut is provided on its under face with an annular groove registering with said vent opening.

V3. vA shower head including a perforated outlet plate and an inwardly flanged top, the flanged top providing a gasket seat and havin@ a vent opening formed therein, a gasket fitting the seat, a threaded pipe connection extending ythrough the gasket and through the flanged top and engageable under the latter, and a nut threaded on the pipe -cennection for compressing the gasket, said nut including a flanged part thatJ extends over .the said flanged top and the vent opening therein. Y

In testimony whereof I atlix my signa ture.

HENRY W. A. LEHNERT.
